Abstract

The present utility model discloses a multi-electrode point spark plug which comprises a central electrode, an insulation porcelain body arranged outside the central electrode, a metal shell arranged outside the insulation porcelain body, and lateral electrodes arranged on the metal shell. The spark plug is characterized in that the top of the central electrode is provided with a plurality of pins which are horizontally arranged outward, the tail ends of the pins are provided with sharp hooks, the lateral electrodes are arranged around the top of the metal shell and are corresponding with the pins one by one. The multi-electrode point spark plug provided has a plurality of flashover points, is stable in igniting, has good igniting effects, is simple in structure, low in manufacturing costs, and easy to produce in large scale. Moreover, as the multi-electrode point spark plug has a plurality of igniting points, fuels can be fully burnt, and the multi-electrode point spark plug has the advantages of energy saving and environmental protection.

Description

A kind of multi-ignition flower plug

Technical field

The utility model relates to a kind of spark plug of multi-electrode igniting.

Background technology

The effect of spark plug is the high voltage pulse discharge of electricity that high-voltage conducting wires (nozzles line) is sent here, and air between disruptive spark plug two electrodes produces electric spark with the mist in this cylinder that ignites.Present spark plug mainly contain the single electrode spark plug and and the multi-electrode spark plug, the single electrode spark plug is the one pole arcing, ignition area is little, simultaneously owing to the reasons such as skewness of mist, is very easy to occur the incomplete drawback of fuel combustion; The multi-electrode spark plug generally all exists interelectrode gap inequality to cause the arcing effect bad, complex structural designs, shortcomings such as manufacturing technique requirent height, production cost height.

The utility model content

The utility model proposes a kind of spark plug of novel multi-electrode igniting at the ubiquitous shortcoming of above-mentioned spark plug.

The design that the utility model is taked is:

A kind of multi-ignition flower plug, comprise contre electrode, be arranged on contre electrode outside insulating ceramic, be arranged on the outer metal shell of insulating ceramic, be arranged on the lateral electrode on the metal shell, it is characterized in that: described contre electrode top has the pin of the outside end of a plurality of levels with sharp hook; Described lateral electrode be arranged on the metal shell top around, corresponding one by one with above-mentioned pin.

Described lateral electrode upper end has pointed cone, and the sharp hook of the pin of contre electrode is corresponding one by one with the tip of the pointed cone of lateral electrode.

Described contre electrode pin is evenly distributed on the same circumference.

Described lateral electrode is evenly distributed on the metal shell top.

Described lateral electrode tip location is a little less than the pin of contre electrode.

The pin of described contre electrode and the quantity of lateral electrode are 2-10.

In sum, the utlity model has following significant beneficial effect: (1) arcing point is many, and igniting is stable, and it is effective to light a fire; (2) simple for structure, production cost is low, is easy to large-scale production; (3) can impel full combustion of fuel, have the advantage of energy-conserving and environment-protective.

Description of drawings

Accompanying drawing 1 is the partial sectional view of spark plug described in the utility model;

Accompanying drawing 2 is the structure chart of sparking-plug electrode described in the utility model.

Embodiment

In order to allow those skilled in the art understand the technical solution of the utility model better, the utility model is further elaborated below in conjunction with accompanying drawing.

As shown in Figure 1, a kind of multi-ignition flower plug comprises contre electrode 1, insulating ceramic 2, metal shell 3, lateral electrode 4; Contre electrode 1 has the pin 11 of the outside end of a plurality of levels with sharp hook; Described lateral electrode 4 be arranged on the metal shell top around, lateral electrode 4 upper ends have pointed cone.

As shown in Figure 2, have sharp hook 111 slightly down on the contre electrode pin 11, lateral electrode 4 tops also have slightly curved pointed cone 41 up, and the bill of sharp hook 111 faces the tip of pointed cone 41; Lateral electrode be evenly distributed on metal shell 3 upper ends around, other pins of contre electrode 1 and other lateral electrodes are corresponding one by one, bill toward each other.

When spark plug is worked, the arcing simultaneously of each limit, ignition range promotes greatly.

In the present embodiment, spark plug is provided with 4 ignitors, and the quantity of electrode can be done some adjustment in actual applications, and the quantity of electrode is 2-10; The relative position of contre electrode and lateral electrode also can change, and for example lateral electrode can be higher than contre electrode.Need to prove; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these changes and distortion all should belong to the protection range of the appended claim of the utility model.
